URL: https://github.com/llvm/llvm-project/commit/035e76ff3706ee3e677fbae67cf47a343cf6eceb DIFF: https://github.com/llvm/llvm-project/commit/035e76ff3706ee3e677fbae67cf47a343cf6eceb.diff LOG: [Serialization] Clear moved-from deque to ensure valid state post-move (#97221) This patch addresses a use-after-move issue, reported by static analyzer tool, by clearing the `PotentiallyInterestingDecls` deque after it has been moved to `MaybeInterestingDecls`. The fix ensures that the subsequent assert statement correctly checks for an empty state, preventing any undefined behavior in ASTReader::PassInterestingDeclsToConsumer().
